CHARGING MEANS FOR GAS-PRODUCERS.

To all whom it may concern:

Be it known that I, NELSON H. HENDER- SON, of Vernon, in the county ofOneida and State of New York, have invented a certain new and usefulCharging Means for Gas- Producers, of which the following isspecification.

My invention relates to gas producers and particularly to means wherebythe fuel can be introduced into the producer without opening theinterior thereof to the outer atmosphere, and it consists in thecombinations and constructions hereinafter set forth and claimed.

In describing this invention reference is had to the accompanyingdrawing in which like characters designate corresponding parts in allthe views.

- Figures 1 and 2 are respectively horizontal and vertical sectionalviews of the eharging means for gas producers and contiguous parts, Fig.1 being taken on line M-M Fig. 2 and Fig. 2 being taken on line X-XFig. 1. I

This means for permitting the introduction of fuel into the producerwithout open- -ing the producer to the outer atmosphere comprises whatis sometimes called a charging door-and includes ahopper lmounted on thet 2 of the producer, a gate 3 for closing t e bottom of the hopper 1, acover or cap 4 for the hopper, and connections between the gate and thecover whereby the 'gate can be opened only when the. cover is inposition, and must be closed prior to the removing of the cover. Thehopper is cylindrical in form and is here shown as provided with abottom 5 having openings 6 therein located diametrically opposite toeach other. The gate 3, in this embodiment of my invention is movableabout an axis coincident with the axis of the hopper and comprisesoppositely extending wings for closing the openings 6, the wings beingmovable into and out of alinement with the bottom 5 to uncover and coversaid opening when the gate is moved about its axis.

The cover or cap at is provided with a cylindrical wall 7 whichencircles the hopper and extends the entire length thereof when thecover is in position, and the lower edge thereof projects into anannular channel 8 containing water for sealing the cover whenSpecification of Letters Patent.

it is in its closed position. The cover is also provided with radiallyextending lugs 9 extending outwardly therefrom and inter looking withmeans as a flange 10 associated with the body of the gas producer, theflange being formed with slots 11 with which the lugs move intoalinement when the cover'is turned for permitting the removing of thecover axially of the hopper for the purpose of permitting fuel to beinserted in the hopper upon the bottom thereof and upon-the gate 3. Thecover is movable about its axis,

which is coincident with the axis of the hopper and the gate, forbringing the lugs 9 into alinement with the slots 11 and for turning thelugs 9 under the flange 10 and thus locking the cover from removalaxially. The connections between the cover and the gate include an axialstem 12 provided on the gate and extending upwardly through a guide 13provided on the bottom of the hopper, the stem coaeting with the coverin order that the stem and, gate may be turned to close the gate whenthe cover is turned to bring the lugs 9 into alinementwith the slots 11or to open the gate when the cover 4 is turned to carry the lugs 9 underthe flange 10. As here shown one of said coacting parts as the cover Lis formed with a noncircular socket 14 for receiving a head 15 providedon the other of said parts as the stem 12, the head fitting the socket.The lugs 9 are thick enough from their lower to their upper faces toprevent the socket 14- engaging the head 15 when the lugs are resting onthe upper face of the flange 10 so that the gate 3 can be turned onlywhen the lugs have passed through the slots 11 in the flange 10. Asuitable handle 16 having a stem 17 connected to the socket is providedfor facilitating the turning of the cover.

In operation when it desired to introduce fuel into the gas producer,the cover 4 is moved about its axis until the lugs 9 are broughtintoregistration with the slots 10 thereby turning the gate 3 so that theopenings 6 in the bottom of the hopper are closed by the gate, and thenlifting the cover off the hopper. The fuel is then placed in the hopperupon the bottom 5 thereof and upon the gate 3 and the cover againplacedon the hopper with the lugs 9 passed through the slots 10 and thecover-turned to interlock the lugs 9 under the flange 10, and to movethe gate 3 to uncover the openings 6 and, permit the fuel to drop intothe gasprodueer.

Vhat I claim is o 1. A charging means for gas producers comprising ahopper having an opening in its bottom, a gate'for opening and closingthe opening, a removable cover for the hopper, means for locking thecover in its closed position, and an operating member operable to unlockor lock the cover and to simultaneously close or open the gate, saidmember being carried by the cover and serving as a handle therefor,substantially as and for the purpose described.

2. A charging means for gas producers comprising a hopper having anopening in its bottom, a gate for openin and'closing the opening, acover for the iopper, means for locking the cover from removal when thegate is open, connections between the cover and the gate, whereby thelocking means occupies' its unlocked. position to permit re moval of thecover only when the .gate is closed, and a single operating membercommon to the cover and the gate and being carried by the cover andserving asa handle by v which the cover is removed and replaced,

substantially as and for the purpose specified.

3. A, charging'means for gas producers comprising a hopper havinganopening in its bottom, a gate for opening and closing the opening, acover for the hopper, powertransmittingconnections between the cover andthe gate, locking means for holding the cover from removal during theunlocking operation and until the gate is closed, and

operating means carried by the cover and v while the gate is closing anduntil the gate is closed, substantially as and for the pur-,

pose described.

5. A charging means for gas producers comprising a hopper having anopening in its bottom, a gate for opening and closing the opening, acover for the hopper, the cover being movableaboutan axis and alsoaxially, power-transmitting connections between the cover and the gatewhereby when the cover is moved about its axis, the gate is opened orclosed, said connections comprising interfitting parts associatedrespectively with the cover and the gate, the part associated with thecover being carried thereby .and movable therewith and serving as ahandle by which the cover is moved axially and locking means for holdingthe cover from removal while the gate is closing and" until the gate isclosed, substantially as and for the purpose specified.
